Polysorbate 40

Polysorbate 40, also known as polyoxyethylene sorbitan monopalmitate, consists of sorbitol, ethylene oxide, and palmitic acid. It has a molecular formula of C62H122O26. At room temperature, it is in the form of a yellow to orange viscous liquid or pastes at room temperature. Polyoxyethylene 20 sorbitan monopalmitate is an O/W emulsifier with an HLB value of 15.6. It is soluble in water, ethanol, ethyl acetate, and toluene.

What is HLB value?

图片
  WHAT IS HLB ? HLB value is the abbreviation for hydrophilic-lipophilic balance, it is the ratio between the hydrophilic portions and lipophilic portion of a surfactant. It is represented by a number between 1 and 20. An HLB value less than 6 indicates that the surfactant favors W/O emulsion; an HLB value greater than 8 favors O/W emulsion. HLB values in between 7 and 9 indicate that the surfactants are good wetting agents. Huana  has been professionally concentrated on Sorbitan  Esters & Polysorbates since 1993, with decades of R&D and production experience.

Differences between polysorbate 20 and polysorbate 80

图片
  W hat I s the D ifference between polysorbate 20 and 80   Synthetic Raw Materials Difference between  P olysorbate 20 80 Polysorbate 20 is a product of the polymerization reaction of sorbitan monolaurate and ethylene oxide, while polysorbate 80 is synthesized by the polymerization of sorbitan monooleate and ethylene oxide.   Application Difference between Polysorbate 20 and 80 P olysorbate 20 uses in cosmetics   is known as a non-ionic stain remover because it has relatively more hydrophilic groups (polyoxyethylene), which gives it a strong hydrophilicity property. Polysorbate 20 is usually used as an oil-in-water(O/W) type emulsifier and solubilizer.   Polysorbate 80 is one of the most common polysorbates. The   polysorbate 80 emulsifier   has significant resistance to electrolyte and strong hydrophilicity, which allow it to be widely used in liquid, semisolid and solid preparations. Polysorbate 80 is used as an oil-in-water(O/W) type emulsifie...
